Ap liatlgfl fil d Se tember 9, 1904. Serial No. 223,939.

To all whom it may concern.-

Be it; known that I, A TON SCHUERMANN,

of the cityof Decatur,county of Macon, and

State oflllinois, have invented a certain new and useful Soft-MetalGasket for Service-' Clamps, of which the following is a specification:L

This invention relates to serviceclamps, used in tapping pipes andforming a permanentattachn ent thereto, and-it provides a gasket whichis always continuous and which may be readily secured to the saddle ofthe clamp.

' The gasket comprises. a circular, or "ap proximately circular ring,preferably circular in cross section, and lugs extending'radially from'thering at opposite points in'the cirshowing the gasket in place.

'cumference thereof The gasketand the lugs .are made of lead, orothersoftmetal, and the entire device is preferably cas'tinte rali Inthe drawings forming art of t is specification Figure l-is a-plan 0 theinner surface of a saddle of a service clamp, showi$ the saddle groovedto receive the'gasket. 112' is a plan of the inner surface of the sad e,Fig. 3 is a side view of a segment of pipeshowin the service clampattached to the pipe. ig. 4 'is an end view of a segment of, pipe, withservice clampattached. Fig. 5 is a plan of the gas' ket, 1 1g. 6 is anelevation,

The clamp saddle 3 is slightly curved or dished on its under side(see-Fig. 4) to approximate the curvature of the ipe 9, and at oppositesides it hasthe usuals otted ears 4, t rough which the threaded ends .ofstrap 7 extend, it has the threaded bore 6,-through i for connecting thegasket with the-saddle of v about midway which the cock is connectedwith the pipe,

.and it also has the groove 5 which forms a seat or hearing forthegasket. I

.The gasket 1 is a'soft'metal- ,p'refe'rably circular incross section,and t e means the service clamp consists of lu s, or extensions, 2,which are preferably at and 'thin and project from opposite sides of thering of its thickness, as seen in Fig. 6, so that they will lie againstthe under face of the saddle and not revent the ring-f y from fittingsnugly .within t e groove 5.

formed of lead'wire bent to shape or edge view of the 5, and it is thenpressed to place in the groove 5 by the fingers ofthe operator and thelugs are bent around'the edges of the saddie at points quartering to theears 4, as

shown in Figs. 2, 3 and 4. Afterthe gasket is thus securely. connectedwith the saddle, the saddle may, be handled roughly, transported,.andfinally placed in any position against the ipe without danger of losingthe gasket or 0 having the gasket become n1isplaced. In applying theservice clamp to the. pipe, -the gasket is-com ressed firmly between-thepipe and-the sa dle bytightening up the. nuts 8 on the strap 7. i

. y The continuityof the ring assures an unbroken gasket, asdistinguished from gaskets d placed endto end, and the cross-sectionaextension of the body of the gasket facilitates the comressi'on of thegasket into inequalities of sur face of the pipe and of the saddle. Iclaim; v ,1. A gasket for service consisting of a continuous ring ofsoft metal which is circular. in cross'section; and inte--gral,-pliable,ffiat, radial lugs projecting from opposite sides thereofand of'lesser thickness anthering'. 2-. a service clamp, the combinationwith the saddle having a dished face provided with a groove, erf ratedears on. opposite sides of the sad e, and a strap engaging said ears forattaching thesaddle to a pipe; of a gasket comprising a soft ring fit-tsaid groove and thicker than its depth, 92% thin, pliable lugsprojectingop ositely from said clamps, the same rin at the center of its tcknessalong the dis ed face of said saddle and engaging the edges of thelatterat points quartering to its ears.

In testimony whereof I sign my name in thepresence of two subscribingwitnesses.
